<p class="IEEEAbtract">As the issue of global warming draws increasing concern, many studies to reduce CO<sub>2</sub> and CH<sub>4 </sub>gases (greenhouse gases, GHG) have been implemented in several countries, including in Indonesia. Considering that Indonesia has a huge numbers of palm oil mills, no doubt if their waste water treatment as one of the major sources in GHG.&nbsp; This paper presents the results from a research project between Metawater Co., Ltd.-Japan and University of Sumatera Utara-Indonesia. The objective of the research is to study the methane emission of thermophilic fermentation in the treatment of palm oil mill effluent (POME) on a laboratory scale. Anaerobic digestion was performed in two-litre water jacketed biodigester type continuous stirred tank reactor (CSTR) and operated at a thermophilic temperature (55 <sup>o</sup>C). As raw material, a real liquid waste (POME) from palm oil mill was used. Fresh POME was obtained from seeding pond of PTPN II waste water treatment facility which has concentration of 39.7 g of VS/L and COD value of 59,000 mg/L. To gain precise results, complete recording and reliable equipment of reactor was employed. As the experimental results, for hydraulic retention time (HRT) 8 days, VS decomposition rate of 63.5% and gas generation of 6.05-9.82 L/day were obtained, while for HRT 6 and 4 days, VS decomposition rate of 61.2, 53.3% and gas generation of&nbsp; 6.93-8.94&nbsp; and&nbsp; 13.95-16.14 L/day were obtained respectively.</p> <p>Keywords<strong>&mdash;</strong>methane (CH<sub>4</sub>), palm oil mill effluent (POME), anaerobic digestion, thermophilic, green house gases (GHG)</p
